A New Framework for Modeling Solar Flares from MHD to Kinetic Processes
Joel C. Allred, Graham S. Kerr, Silvina E. Guidoni +4
Physical processes in solar flares span many orders of magnitude in spatiotemporal scales, so a single unified model accounting for all relevant processes remains computationally i…
Flare Impulsive-phase Durations
Brian R. Dennis, Hugh Hudson, Joel Allred
This Research Note is in response to the recent paper by S. M. Perriyil et al. (2026). They provide measurements of the time delay (delta t) between the hard X-ray and soft X-ray p…
Fe I 6173 Å Emission During White-Light Solar Flares
Samuel Granovsky, Alexander G. Kosovichev, Viacheslav M. Sadykov +2
Between 2017 and 2024, the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory has observed numerous white-light solar flares (WLFs). HMI spectro-polarime…
Solar Flare Ribbon Fronts. II. Evolution of heating rates in individual flare footpoints
Graham S. Kerr, Vanessa Polito, Yan Xu +1
Solar flare ribbon fronts appear ahead of the bright structures that normally characterise solar flares, and can persist for an extended period of time in spatially localised patch…
An Optically Thin View of the Flaring Chromosphere: Nonthermal widths in a chromospheric condensation during an X-class solar flare
Graham S. Kerr, Adam F. Kowalski, Joel C. Allred +2
The bulk of solar flare energy is deposited in the chromosphere. Flare ribbons and footpoints in the chromosphere therefore offer great diagnostic potential of flare energy release…
Investigating the response of loop plasma to nanoflare heating using RADYN simulations
V. Polito, P. Testa, J. Allred +5
We present the results of 1D hydrodynamic simulations of coronal loops which are subject to nanoflares, caused by either in-situ thermal heating, or non-thermal electrons (NTE) bea…
Forward Modeling of Synthetic EUV/SXR Emission from Solar Coronal Active Regions: Case of AR 11117
V. S. Airapetian, J. Allred
Recent progress in obtaining high spatial resolution images of the solar corona in the extreme-ultraviolet (EUV) with Hinode, TRACE, SDO and recent Hi-C missions and soft X-ray (SX…
